MACHINE FOR WASHING PIECE GOODS.

Specification of Letters Patent No. 11,329, dated July 18, 1854:.`

' is a view of the fan wheel or dasher detached from the vat.

Heretofore woven fabrics have been washed by being passed through vessels furnished with a continuo-us supply of fresh water, either twisted into a rope or in single sheets and have only been acted upon by mere rinsing `or squeezing. i

Our improvement consists in an arrangement of rollers and of revolving dashers in combination with a vat whereby several continuous layers of cloth can be simultaneously passed through and acted upon by the water; thus effect-ing an economy in time and room and securing a more thorough washing of the material.

A, B, C, D, Fig. 2, represents a longitudinal vertical section of the improved washing vat.

E, F, G, H, Fig. 2, is a transverse vertical section of the frame inserted in said vat. The frame E F G H is made of wood and extends the` whole length inside of said vat. To this frame a series of wooden and metallic rollers a a a a am and a lower series b b b b bi", &c., are attached.

K and L are a pair of drawing and squeeze rollers for the `purpose of drawing the fabric into the vat.. M and N are also drawing and squeezing rollers for the purpose of dra-wing the fabric through the vat.

The fabric enters at K and L in live parn allel and continuous layers, passes over the roller L and under the roller b. The upper layer of fabric passes around b ascends and passes over a",' the second layer passes .around b ascends and passes over a,' the third layer passes around b" ascends and passes over am; the fourth layer passes around biv and aiv; the fth passes around bv and av. As these layers pass over a a a af civ c" respectively they meet and move on together through the drawing and squeeze rollers M and N.

c c c 0 civ &c. lare a series of small dashers composed of a metallic shaft with wings or vanes e, QJ, fu, o, extending radially outward. These vanes are made of sheet iron or copper and are attached to the me* tallic shaft. These dasher wheels so made are placed in the respective positions shown at c c c 0 civ Fig. 2. They have pulleys at their extremities and are geared to the machinery so as to revolve rapidly. The level of the water is kept just below the axle ofthe dasher wheels.` As the fabrics in single continuous layers pass along by the dasher wheels therapid revolution of the dasher wheels drivesthe water through the single thickness of fabric and thus rapidly and effectively cleanses it.

The operation of ourimproved washing vat is as follows: The fabrics in five parallel and continuous layers enter between K and L; the layersY are distributed and pass around the rollers b b b b'" biv and over a a a a" civ av as shown in the drawingFig. 2. Each layer is separately exposed to the action of the water in the vat; and as each one passes the revolving dasher wheels c c c 0 01V 0'` the wa` ter'is thereby forcibly driven through o-r against each separate layer. Afterward the live layers of fabric `together pass between the drawing and squeezing rollers M N and are squeezed. The water is constantly changed in the vat in the ordinary manner. The number of rollers and dasher wheels may be changed without altering our invention provided the same arrangement and' combination of parts be preserved.

What we claim and desire to secure by Letters Patent is- The combination of the series of distributing rollers a a a &c., b b b &c., and the dasher wheels c c 0 &c., with the vat in the manner and for the purpose substantially as hereinbefore described.
